Mathematics
1 answer:
vodka [1.7K]3 years ago
3 0

Answer: Subtract the sum of the two angles from 180 degrees. The sum of all the angles of a triangle always equals 180 degrees. Write down the difference you found when subtracting the sum of the two angles from 180 degrees. This is the value of X.

Step-by-step explanation: To find the value of x, bring the variable to the left side and bring all the remaining values to the right side. Simplify the values to find the result.

What does an isometric transformation do?
BaLLatris [955]

Answer:

Option: B is correct.

( Preserves the shape and size of the figure )

Step-by-step explanation:

  • An ISOMETRIC TRANSFORMATION (RIGID MOTION) is a transformation that preserves the distances and/or angles between the pre-image and image.
  • The isometric transformations are reflection, rotation and translation and combinations of them such as the glide, which is the combination of a translation and a reflection.

Hence, option B is correct.

Preserves the shape and size of the figure.

May someone please help me out please?
Zanzabum

Step-by-step explanation:

First, we need to find that top angle, which we'll call angle x. We can say 26 is the hypotenuse, and 12 is the adjacent, so we know that:

\cos(x)  =  \frac{12}{26}

Let's solve this, to find X:

x =   { \cos }^{ - 1}( \frac{12}{26} )

Now that we know what X is, we can use trig to find the missing side, which we'll call y. 48 is the adjacent, and y is the hypotenuse, therefore:

\cos(x)  =  \frac{48}{y}

To find y, let's rearrange:

y =  \frac{48}{ \cos(x) }

And now let's figure out calculate the value of y (I'm leaving the value of X as just X for the equations, but you will need it to calculate first):

y = 0.767833242
